Definitions
- This invention relates to the use of a specific carcinoma associated antigen/hapten of carbohydrate nature, fucosylsialosylgangliotetraose-IV 2 ⁇ Fucll 3 ⁇ NeuAcGgOse 4 -(IUPAC-IUB Lipid Document, 1977) for diagnostic and therapeutic procedures related to human lung cancer (small cell carcinomas).
- glycoconjugates carbohydrate structures
- the cell surface carbohydrates are linked either to a lipid moiety, in which case they are called glycolipids, or to peptides (proteins), in which case they are called glycopeptides (glycoproteins).
- Tumor-associated glycoconjugate antigens are previously known in relation to human cancer disease. In melanomas the carbohydrate structures disialosylgangliotetraose and disialosyllactose have been identified linked to a lipid portion. Two carcinoma associated antigens CEA (carcinoembryonal antigen) and GICA (gastrointestinal cancer antigen) have been demonstrated particularly in gastrointestinal carcinomas while a third antigen, CA-50, seems to have a more general distribution. All the antigens are shedded from the cell surface or secreted from the tumor cell and can be demonstrated in blood serums by means of immunological methods.
- CEA carcinoma associated antigen
- GICA gastrointestinal cancer antigen
- the present invention is based on the discovery that patients with certain forms of lung cancer (small cell carcinomas or oat-cell carcinoma) express in the primary lung tumor and its metastases an acidic glycolipid, which is not expressed in normal lung tissue.
- This glycolipid antigen is a ganglioside with the complete chemical structure Fuc ⁇ 1-2Gal ⁇ 1-3GalNAc ⁇ 1-4(NeuAc ⁇ 2-3)Gal ⁇ 1-4Glc-Cer or IV 2 aFucll 3 ⁇ NeuAcGgOse 4 Cer with the short designation Fuc-GM1 (IUPAC-IUB Lipid Document, 1977).
- This ganglioside was first isolated from bovine brain (Ghidoni et al., J. Neurochem.
- ganglioside Fuc-GM1 in pure form from human cancer tissue and from animal organ.
- the purified ganglioside has by a special device obtained an increased immunogenic activity and then been used for the production of monoclonal antibodies.
- Procedures have, within the scope of the invention, been developed for the identification and quantitative determination in tissues, tissue sections, cytological preparations and various body fluids. All of these methods for diagnostic purposes are based on the fact that the antigen can be detected and quantitatively determined by the reaction with specific antibodies produced against the pure ganglioside antigen, Fuc-GM1.
- ganglioside antigen can be measured: surgical or autopsy material of lung, liver, brain or similar organs, cytological specimens obtained by biopsy of lung or other organs, where signs of cancer metastases can be suspected, cells, obtained by aspirations of the respiratory tract, expectorations, or by puncture of pleural or abdominal cavity, biological fluids like whole blood, blood plasma or serum, lymph, cerebrospinal fluid, urine, saliva or similar.
- the antigen which Is used in the present invention is termed, fucosylsialosylgangliotetraose and has the following chemical structure: Fuc ⁇ 1-2Gal ⁇ 1-3GalNAc ⁇ 1-4(NeuAc ⁇ 2-3)Gal ⁇ 1-4Glc or IV 2 ⁇ Fucll 3 ⁇ NeuAcGgOse 4 (IUPAC-IUB Lipid Document, 1977).
- all antigens, which have been modified by the removal of the terminal glucose moiety or by the substitution of the sialic acid (NeuAc) moiety to the N-acetylgalactosamine (GaINAc) moiety instead of to the galactose (Gal) moiety are covered by this patent application.
- the monoclonal antibodies referred to in the present invention have all been produced from antigens bound to a lipid group (acylsphingosine) but this claim will also include the binding of the antigenic group to every other compound.
- the antigen which has been used in the present invention can be isolated from tumor tissue, obtained by surgery or autopsy of patients with lung small cell carcinoma.
- concentration of the antigen in the tumor tissue is in general relatively low, particularly when the patient has been treated with cytostatic drugs, and the isolation of the antigen will then be laborious.
- another biological material which can be used for the isolation of the cancer antigen.
- high concentrations of the ganglioside antigen is formed in the pig's central nervous system, particularly In the dorsal root ganglia.
- the cancer associated ganglioside antigen can then be relatively simply isolated from brain and dorsal roof ganglia.
- gangliosides - it means glycolipids containing sialic acid - are poor immunogens and it has been difficult to produce antibodies with high affinity and specificity against them. This difficulty has been circumvented in the present invention by the adsorption of the ganglioside antigen to a bacterial membrane with known high immunogenic activity. By this device a large number of monoclonal antibodies with high specificity and affinity against the cancer antigen have been produced.
- the present invention concerns in accordance herewith a procedure for the induction of the cancer associated antigen fucosylsialosylgangliotetraose in the nervous system of a particular type of miniature pig, isolation of the antigen with chromato- graphical methods and production of monoclonal antibodies against the purified antigen adsorbed to a certain bacterial membrane.
- the invention includes also the use of the compound fucosylsialosylgangliotetraose and all the derivates of this substance and all types of antibodies directed against them for the diagnosis of different cancer forms, specially certain forms of lung cancer, and for the treatment of the cancer disease in patients.
- Miniature pigs type Göttingen, with a weight of 20-30 kg, were given a diet, in which the regular fodder was supplemented with 30 g chloroquine diphosphate per kg fodder.
- the different ingredients were mixed under the addition of water and after careful mixing the fodder was pelletted and dried.
- the pigs were given this fodder for 2 months and were then slaughtered (bieed- ing under narcosis).
- the whole nervous system was collected, including retina and dorsal root ganglia. Brain and dorsal ganglioa + retina were processed separately, since dorsal ganglia and retina had approx. 20 times higher concentration of Fuc-GM1 than brain.
- the tissue was homogenized after the addition of 3 volumes of water to one volume of tissue material. After homogenization with a knife homogenizer at 1500 rpm during 3 min., 10 volumes of methanol was added under continuous stirring. Then 5 volumes of chloroform were added. After extraction for 1 h the clear supernatant was isolated by centrifugation at 2000 rpm. To the supernatant was added water to give a final chloroform-methanol-water ratio 4:8:5.6 (by volume). After mixing in a separatory funnel, two distinct phases appeared. The upper phase was collected and evaporated to dryness after the addition of 0.1 1 volume or butanol to prevent foaming.
- the evaporation was performed with a rotaratory evaporator under gentle warming on a water bath, the temperature not exceeding 50°C.
- the residue was added 0.5 volume methanol per volume original tissue and 0.5 volume of 1.0 M potassium hydroxide and was left overnight at room temperature.
- the alkaline solution was neutralized to pH 8 with 1.0 M hydrochloric acid and was then allowed to dialyse against running tap water for 48 hours.
- the dialysed crude ganglioside fraction was evaporated (lyophilized) and dissolved 1 volume of chloroform-methanol-water with a volume ratio of 60:30:4.5 per volume original tissue.
- a column (inner diameter 20 mm) was packed with Spherosil-DEAE-dextran, 0.2 volume of resin per volume of original tissue.
- the dialysed ganglioside extract was added slowly to the column and the column was then eluted with 10 bed volumes of chloroform-methanol-water (60:30:4.5, by volume).
- the monosialoganglioside fraction was eluted with 10 bed volumes of 0.02 M potassium acetate in methanol.
- the monosialoganglioside fraction was evaporated and desalted by dialysis against distilled water.
- silica gel (latrobeads ®) was used for each g of original nervous tissue.
- the gel was suspended in chloroform-methanol (volume ratio 4:1) and poured into a glass column with a sintered glass filter and a diameter of 15-20 mm depending on the amount of gel.
- the ganglioside fraction was dissolved in 10 ml of chloroform-methanol-water (65:25:4, by volume) and applied to the column. It was eluted first with 15 ml of chloroform-methanol-water (65:25:4, by volume) for each g (weight/volume) of gel, which was collected in one fraction.
- Fuc-GM1 The final purification of Fuc-GM1 was achieved by preparative thin-layer chromatography.
- Ganglioside (5 ⁇ moles) was applied on a thin-layer plate (20x20 cm, 0.25 mm thick, Merck, AG., Darmstadt), which was developed for 60 min with chloroform-methanol-2.5 M ammonia at 21°C. After completed chromatography the plate was sprayed with 0.01% bromthymol blue in water and the Fuc-GMI band was scraped off.
- the ganglioside was eluted from the gel with chloroform-methanol-water (30:60:20, by volume) and was added one drop of 0.1 M potassium hydroxide dissolved in methanol and evaporated to dryness.
- the pure ganglioside Fuc-GM1 was kept dry in a vacuum desiccator or was dissolved in a small volume of chloroform-methanol (2:1, by volume) and was kept in a teflon capped tube in the dark at +4°C.
- the purified ganglioside Fuc-GM1 from Example 1 was adsorbed to acid-washed Salmonella Minnesota bacteria before immunization according to the principle, described by Young, W.W. and collaborators (J. Exp. Med. 150, 1008-1019, 1979).
- mice 6-8 weeks old, were immunized intravenously with 5 ⁇ g of ganglioside Fuc-GM1, adsorbed to 50 ⁇ g acid-washed Salmonella Minnesota bacterial membranes, suspended in 100 ⁇ l of phosphate-buffered physiological saline, pH 7.4. A new immunization was performed after two weeks with the same dose of immuno- gen under identical conditions (booster dose).
- the spleen cells taken from the immunized mice were fused with mouse Sp 2/0 myeloma cells.
- the resulting hybridomas were expanded, tested and cloned according to the protocol, devised by de St. Groth and Scheid- egger (J. Immunol. Methods, 1-21, 1980).
- the culture medium was collected from each microtiter well with growing hybridomas to determine those secreting antibody specific for Fuc-GM1.
- the determination was performed in an ELISA system according to the following procedure: Fuc-GM1, 50 pmol dissolved in 50 ⁇ l of methanol, was added to the wells of a polyvinylmicrotiter plate and evaporated to dryness.
- the Fuc-GMI positive/HuLy-c negative hybrids were cloned by limited dilution and expanded. The culture medium was collected and used for additional tests without further processing. The isotype of the antibodies produced by each clone was determined by single radial immunodiffusion in agarose containing isotype specific antimouse immunoglobulins.
- the Fuc-GM1 positive/HuLy-c negative hybridomas were cloned and screened to determine those secreting antibody specific for Fuc-GM1. The determination was performed in a double antibody solid phase radioimmuno assay. Fuc-GM1 and a large number of different neutral glycolipids and gangliosides were dissolved in methanol and pipetted into the wells of microtiter plates. After evaporation of the solvents the antigen coated wells were incubated with the monoclonal antibodies. Bound antibody was detected with 125 I-labelled antimouse immunoglobulin; 125 I-antimouse IgM or 125 I-antimouse lgaF(ab) 2 fragment. Each monoclonal antibody was tested against Fuc-GM1; a standard mixture of human brain gangliosides, normal lung tissue, neutral glycolipids and gangliosides.
- the specificity of the monoclonal antibodies were also determined by thin-layer chromatographic immunostaining of the glycolipid antigens.
- the total neutral and acidic glycolipid fractions from a number of organs were separated on aluminia-backed high performance thin-layer plates (HPTLC) and incubated with the monoclonal antibodies of the Fuc-GM1 positive hybridomas, diluted with Tris buffer-1% BSA (0.05 M Tris, 0.14 M NaCI, pH 7.8, containing 10 g bovine serum albumin/I and 100 mg merthiolate/I).
- Bound monoclonal antibody was detected with 125 I-labelled antimouse immunoglobulin and then exposing it to X-ray film for 12-24 h.
- the antibodies were applied to the plate by soaking cellulose acetate strips in the antibody solution and covering one lane of the HPTLC-plate with the strip.
- Tissue approx. 0.1 g
- Tissue was homogenized together with 0.5 ml of water in a small conical tube tissue grinder with teflon pestle in an ice bath.
- 1.6 mt of methanol and 0.8 ml of chloroform were added.
- the clear supernatant was transferred to a Kimax-tube with teflon cap.
- the sediment was suspended in 0.5 ml of water and then 1.6 ml of methanol and 0.8 ml of chloroform were added.
- a portion of the antigen fraction was dissolved in methanol and 50 ⁇ l of extract was pipetted into the wells of a polyvinyl microtiter plate. Standard solutions of 0.5 to 5 pmol of pure Fuc-GM1 in methanol was added to other wells. The solvent was evaporated under a stream of nitrogen. To the unknown samples and standards 10-100 ug of monoclonal antibody, specific for Fuc-GM1 and produced as described in Example 2, dissolved in PBS/BSA was added. The samples were incubated for 1 h at room temperature. The wells were washed 3 times with PBS solution and then 125 I-labelled antimouse-immunoglobulin was added and allowed to react for 3 hours.
- Fuc-GM1 has been detected in 19/20 lung small cell carcinoma.
- the antigen has not been identified in other forms of lung carcinomas (squamous cell, large cell or adenocarcinoma) neither in carcinomas of mammary gland, stomach, colorectal mucosa, urinary bladder or uterus. Traces of the antigen has been shown in normal and carcinomatous pancreatic tissue.
- the concentration of tumor antigen was determined with a double solid phase antibody method, at which the antigen was adsorbed to the solid phase and determined with the specific monoclonal antibody (Example 2) and antimouse-immunoglobulin.
- Fuc-GM1 (20 pmol) and the purified antigen fraction of unknown serum samples were dissolved in methanol and serial dilutions of them (1/2-1/2048) were pipetted in the wells of polyvinyl microtiter plates (Flow Laboratories art.nr. 77-173-05) and were evaporated. Unspecific binding of the wells was blocked with 20 ⁇ l of 1% BSA in PBS and then 50 ⁇ l of specific monoclonal antibody, diluted in 1% BSA in PBS, was added.
- the antigen was only detected in blood serum of patients with lung small cell carcinoma.
